If you arrive late wednesday, I doubt we can get ignition installed
and dyno'd Thursday in time to make it for the test day at sebring

Dyno Friday and forget test day?

If you can get to it a spacer under the rubber bumper around the shock
shaft will increase the rear roll stiffness. This can be something
simple
like masking tape rolled around the shaft to a thickness of .5 to .75
It might take a whole roll of masking tape
